Well, I'm glad you handled it well, I'm happy it wasn't a problem, but that's not the case for others unfortunately. Neglecting children is a pretty serious thing, it can lead to a lot of kids acting up and misbehaving and just in general doing bad things because they don't get the necessary care and attention by people at home. You behaved rather well considering it, whereas other kids can just as easily fight, and get into a lot more trouble because they just don't get any attention at home.
Unfortunately the lack of attention was a problem for us, especially with a lot of very competitive boys roaming around the house, and you are right that when everybody grew up we realised it really wasn't that much of a problem, but it is a problem at the time, and I personally wouldn't want that problem for any of my children because it led to not a very nice, warm, loving household to be around. Mummy loves everyone equally and does everything for everyone equally. We never all sat down at the table with a meal or anything, and that's what I would have loved. Also, I didn't have both a mum and a dad, there weren't two parents there. Just the one. Caused problems I'd never want to see happen for any children I'd have, even if, in years to come, they'd be okay with it. I'd rather there be nothing bad, in time, they'll become okay about, and I'll try everything I can to do that.
So, really, I do think siblings are good, but I think people have too many and then can't give each child and care and attention they deserve. Some kids don't need that stimulation, especially in today's age of computers and the Internet, but I'd rather not bank on that being the case, or that they'll handle the lack of attention in a nice manner, and not an extremely self-destructive way.
